Nutshell Granules
Nutshell granules are the softest medium in the range: a reusable organic abrasive made from walnut shells, produced by Kuhmichel Abrasiv. In 25 kg bags there are 11 items to choose from.
Material and technical data
The granulate is made from crushed, cleaned and screened walnut shells. It is far softer than any mineral abrasive and removes practically nothing from the base material. Being elastic, it deforms on impact and transfers its energy to the layer on top rather than to the part underneath.
Grain sizes and applications
Typical jobs are paint stripping, deburring, degreasing and cleaning on parts that must stay dimensionally accurate: moulds and tools, engine components, turbine parts, sensitive surfaces in aluminium or plastic. As a reusable medium it runs many cycles until the grain has become too fine.
Why the 25 kg bag
Nutshell granules also run in a circuit and are consumed only slowly. The 25 kg bag is the right size for most machines, all the more so because the granulate is light and one bag fills a large volume. Anyone running several cabinets takes the pallet. Further grades in this unit: bagged goods.
What matters when choosing
The limit is hardness: firmly adhering scale or baked-on coatings will not come off with nutshell granules. It is the medium of choice when the part must be spared — and the wrong choice when substance has to be removed.
Alternatives in the range
Where the surface is to be compacted rather than removed, Glass Beads are the alternative. For removal work Asilikos and Silicon Carbide are available. Every grade side by side is in the blasting media programme.
